Dehydrated Onions have been produced in small quantities since the nineteenth century. Onion is an important vegetable crop grown in India and forms a part of daily diet in almost all households throughout the year. India is the second largest producer of onion in the world. Onion is one of the most important but perishable groups known. It is also used for medical purpose. But due to non-availability of appropriate post-harvest storage facilities, 20-25% of the total produced onions are wasted, which in terms of value amounts to crores of rupees. Unprocessed foods are susceptible to spoilage by biochemical processes, microbial attack and infestation. The right post harvest practices such as good processing techniques, and proper packaging, transportation and storage (of even processed foods) can play a significant role in reducing spoilage and extending shelf life. Among various methods of preservation, dehydration of vegetables is one of the most popular and oldest methods. Dehydration increases the storage period of vegetables and make them available throughout the year and even in off-season, thus supplying the important nutrients in a concentrated form. Dehydrated foods are more concentrated source of minerals than any other preserved form of foodstuff. Almost all dehydrated onion products like-kibbled, sliced, rings (half & full), large kibbled, minced (in various cut sizes), chopped, granulates and powder forms are not new to households & restaurants. It has good potential in food processing industries, defense, pharmaceutical industries, hotels and restaurants, caterers, etc. In the food processing field, dehydration is sometimes described as the removal of 85% or more of water from a food substance, by exposure to thermal energy by various means. The main advantages of dehydrated onions are that they are easy to store, being lighter in weight and smaller in bulk than fresh or other processed onions. They are cheap to pack compared with canned goods. They do not require refrigerated storage as do frozen onions and the contents of a container can be used some time after opening provided they are not dehydrated. Dried onion is now available in market in the powdered or kibled form. The composition of the fresh and dried forms is given. The kibbled form has moisture content of about 10% microscopically onion powders shows abundant parent chymatous cells. In India dehydration of many food products especially vegetables and some fruits are in practices at home and industry level throughout year. As a whole the products have fair market demand. There is a good scope and good market potential in such products and new entrepreneurs should venture in such projects.
